*Thisiiifvention relates to sick beds with closet arrangement, which renders it possible for the patiehtto attend to-his requirements :Whilst'iii bed. F or'this purpose arrangements ai'e'already'lt'riown, wherein an" aperture is provided in'the mattr'ess, in which the chamber' c'an b'efintr'oduced in any suitable manner.

The objections to these known devices consist in' that insufficient provision is made to render them o dburless and to construct the arrangement so that the patient can operate same without assistance.

In order toovercome these objections a tight closure of the mattress aperture during andafter useof the device and until the chamber emptied, is provided. The device is so constructed that it can be operated by the patient with the least possible effort.

. This problem is, solvedaccording to the invention by rain discs which are controlled by rope or chain pulling elements, by means of whichthe mattre part filling the mattress apertiiifeis positivelycohfnectd to'the chamberin such ainan'ner that, when the mattress part is removed, the chamber is brought into position and, when the chamber is removed, the mattress part is returned into the aperture.

An embodiment of the invention is illustrated by way of example in the accompanying drawings, in which Fig. 1 shows the device in side elevation, partly in section with the chamben in position for use.

Fig. 2 is a cross section of the device with the mattress part in closing position.

Fig. 3 is a top plan view of Fig. 2.

The removing and returning of the mattress part and of the chamber is effected in a very convenient manner by the patient, even when in recumbent position, by means of pull cords 1. These cords 1 extend over pulleys 2 and 3 under the mattress 4 and are separately wound and unwound on a common drum 5.

' The drum 5 is mounted on a shaft 6 with a the hollow shaft 9. On the head of this bolt 11 a lever 11a is mounted on a pin 11', and on the other end of this lever a fork 11b is arranged which carries the filling P for the mattress aperture. This filling P, shown in Fig. 2, fills a corresponding aperture in the mattress 4. The oscillatable arm 11a slides with a roller 110 on the inclined edge of the cam 10 in such a manner that, when one of the pull ropes 1 is actuated through the intermediary of the drum 5 and the gearing 7, 8, the hollow shaft 9 and the cam disc 10 rigidly connected thereto are rotated so that the filling P descends on the race of the cam 10 vertically out of the mattress aperture. This operation continues until the roller 11c comes into the cavity 10a of the cam 10, by which the bolt 11 is rotated. Owing to this rotation the filling P is turned downwards and aside, so that it is removed from under the mattress aperture. In order to prevent the bolt 11 and therefore the filling P from turning too far. the bolt 11 has on its lower end an abutment 11d, which prevents further movement after having been rotated through a certain angle by abutting against the transverse frame 12 of the bed.

A swinging in of the chamber correspondin g to the swinging out of the filling is eflected at the same time by a rope or chain gearing, preferably crossed according to the position of construction and comprising two wheels 13 and 14 and a chain or rope 15. The construction of the turning device for the chamber 16 is similar to that of the arrangement for inserting and rr-imoving the filling P.

The chamber 16, when not in use, is pressed tightly under a cover 1611 fixed on the bed fran'ie. During the vertical removal of the filling P from the mattress, the hollow shaft 20 with cam disc 19 is driven by wheels 13 and 14 and rope or chain 15.

A vertical bolt 20?) is mounted in a hole of the shaft 20, on the head of which bolt a lever 19 is hinged with a roller 17correspending; to roller 110 of lever 11aand to the lower end of this shaft 20 an abutment 20a is rigidly connected. Owing to turning of shaft 20 and disc 19 roller 17 slides down an inclined edge of disc 19 and turns chamber 16 downward bringing it out of contact with cover 1606. During the further movement effected by a. chain or rope 15, the roller 17 of the hinged lever 18 comes into a cavity 19a in the cam disc 19 so that the bolt 20?) and its abutment 20a is rotated until this abutment bears against the transverse frame 12. Vhen this has been effected, the chamber is situated directly under the mattress aperture. If further rotation is imparted to the vertical shaft 20, a vertical lifting of the chamber 16 in the direction of the mattress aperture is effected by the cam race of the cam disc 19.

After use, the patient h as merely to change the pulling elements so that the reverse operation to; that described is effected, namely the chamber is first vertically lowered and, when the roller 17 comes into the cavity in the cam disc l9, is rotated until the abutment 20a returns into its original position against the frame 12. The roller 17 then leaves the cavity in the cam disc 19 during the further rotation of the vertical shaft 20 and climbs up the second inclined edge of this cam disc. In this manner the lever 18 is turned upwards and the chamber 16 pressed with its upper edge against the cover 16a by means of the raised portion of the cam 19.

A hermetic and consequently odour-less closing is effected by suitable means. The swinging of the filling P into its initial position is effected in a similar manner.

In order to hold the chamber 16 permanent-- ly in vertical position it is connected with a how 21, weighted by a weight 216; and suspended in a forl: 22.

The vertical shaft 9 and also the shaft 20 are mounted in suitable manner on ball bearings to obtain a silent and free running.

I claim:

1. A sick bed with closet arrangement, comprising in combination a mattress having an a perturc, two vertical rotatable hollow shafts,

one on each side of said aperture, cam discs on each of said shafts, rotatable bolts extending through said hollow shafts, a bifurcated lever hinged on the upper end and an abutment connected rigidly to the lower end of each of said bolts, mattress filling carried by one of said lever-s, a chamber suspended on the other of said levers and a roller on each of said levers adapted to slide along the edges of said cam discs, said edges having a cavity by which said levers are driven to turn horizontally with said fillingand chamber until said abutments bear against. the bedirame and prevent further turning, so that said cam discs may slide under said levers. and their rollers, and swing them up or down, said cam 1 eiscs being disposed with respectto. each other in such manner, that, as said hollow shafts with cams are moved simultaneously through a linkage connecting them, said filling and said chamber are alternately moved to and into or from and out of the aperturein said mattress, so that said chamber israised into the aperture when said filling is swung away from it and conversely. v ,1 5

2. A sick bed with closet arrangementas specified in claim 1, comprising in combination with the chamber andrcam associated therewith, a cover for said; chamber,,fasten ed under the bed frame, and the edge of said cam disc having a, second inclinedpartadapted to press said chamber against said cover upon.
